Abstract

A ski binding including a front jaw, a heel holder and a connecting element consisting of two partial sections. The front jaw is slidingly movably supported in a ski-fixed guide rail and can be fixed in predetermined positions. The guide rail has a locking element with which the front partial section can be fixed. In order for the manufacturer to connect in this ski binding the guide rail for the front jaw and the front partial section to form one unit for easy transport, the front partial section of the connecting element has a cover with at least two locking members which engage corresponding recesses in the guide rail, the two locking members being reciprocally active against one another in vertical planes so as to prevent an inadvertent unlocking.

Description

FIELD OF THE INVENTION

The invention relates to a ski binding having a front jaw and a heel holder connected together by a multiple part metal band.

BACKGROUND OF THE INVENTION

Such a ski binding is already known through products available on the market and is, for example, disclosed in the "ess news Catalog 1988" (published in connection with the ISPO '88 in Muenchen) and in the DE-OS 31 09 754 and in DE-GM 82 05 134. The connecting element is in this design divided into two partial sections for the purpose of adjusting the binding to various shoe sizes. One partial section of the connecting element had for this reason some type of serrated slats with which or from which two bolts of the other partial section, which bolts are flat on one side, could engage or disengage. To make this adjustment of the ski binding, the cover had to be removed and had to be put back in place after the adjustment had been completed. A screwdriver was needed for this in order to remove the cover and to disengage and engage the bolts.

The ski binding according to AT-PS 392 215, which has an undivided connecting element, has on the underside of the guide rail for the front jaw a square pin which is received in a square hole of the connecting element, which moreover has a row of holes having circular cross sections. This measure, however, does not create a permanent connection between the guide rail and the connecting element.

The brochure of the Tyrolia company 91/92 (No. 009072-12/90, distributed from Feb. 28 to Mar. 3, 1991 at the ISPO '91 in Muenchen) describes a ski binding in which the metal band is designed so that it is divided into two halves to make packaging easier. The end of one partial section carries two downwardly projecting bolts, each having a head, with which bolts are associated two keyhole-like recesses at the end of the other part. This design was, however, designated for use with a front jaw which was fixedly connectable on the ski. Furthermore, the rear partial section of the metal band carries the heel holder.

SUMMARY OF THE INVENTION

In general, the objects and purposes of the invention are met by a ski binding including a front jaw, a heel holder and a connecting element consisting of two partial sections. The front jaw is slidingly movably supported in a ski-fixed guide rail and can be fixed in predetermined positions. The guide rail has a locking element with which the front partial section of the connecting element can be fixed. In order for the manufacturer to connect in this ski binding the guide rail for the front jaw and the front partial section to form one unit for easy transport, the front partial section of the connecting element has a cover with at least two locking members which engage corresponding recesses in the guide rail, the two locking members being reciprocally active against one another in vertical planes so as to prevent an inadvertent unlocking after they have been connected together.

DETAILED DESCRIPTION

A ski binding arranged on a ski 2 is identified in its entirety by the reference numeral 1 in the drawings. The ski binding 1 includes a connecting element 3 designed as a metal band, a heel holder 4 which is guided in a guide rail 5 fastened on the ski 2 by means of screws 8b, and a front jaw 6 which is supported adjustably and fixably in a further guide rail 7 and which is fastened on the ski 2 by screws 8a. The guide rail 5 of the heel holder 4 is connected to the metal band 3 with the heel holder 4 being lockable in different positions relative to the metal band 3. The metal band 3 consists of a front partial section 3a and a rear partial section 3b. A cover 9 manufactured of plastic is mounted on the front partial section 3a.

The guide rail 7 has three holes 7a to receive the fastening screws 8, and a row of holes 7b into one of which can be selectively received a cylindrical locking pin of the front jaw 6. Two holes 7c are recessed into the rear end of the guide rail 7, the purpose of which holes will be discussed in detail later on. A rearwardly open recess 7d is furthermore provided in the rear end of the guide rail 7. A projection 7e extends in the center of the recess 7d. A rectangular recess 7f lying approximately in the same transverse plane as the two holes 7c is provided in the projection 7e. A snap hook 9a arranged on the cover 9 extends from above into the recess 7f.

A square pin 7g is provided on the guide rail 7 approximately between the two oppositely lying holes 7a. A rectangular recess 7h is provided in the center of the guide rail 7, the front narrow side 7h₁ of which recess 7h carries a downwardly bent and rearwardly directed hook 7i.

The front partial section 3a of the metal band 3 is associated with the guide rail 7. This partial section 3a has a rectangular recess 3c at its front end and has at its front end a transversely extending, upwardly bent web section 3d formed as by stamping. This web 3d rests in the mounted state of the ski binding 1 on the hook 7i of the guide rail 7. A square hole 3e is provided in the front partial section 3a spaced from the recess 3c, into which hole is received the square pin 7g of the guide rail 7 as soon as the guide rail 7 and the front partial section 3a of the metal band 3 are being assembled. The front partial section 3a is designed tapered at its rear end 3f and is provided with a sleeve 10.

Two horizontal attachments 9b exist on the front side of the cover 9 carrying upwardly extending locking pins 9c which, during the assembly of the guide rail 7 and the front partial section 3a, extend from below into the holes 7c of the guide rail 7. In order to facilitate the engagement, both the locking pin 9c and also the snap hook 9a are sloped at their front edges. The cover 9 carries one pair of opposing flaps 9d at its front and at its rear end, which flaps 9d guide the cover 9 onto the front partial section 3a or rather on its sleeve 10. The path of movement of the cover 9 onto the front partial section 3a is limited in one direction by the abutment of the front side of the sleeve 10 and of a section 9e of the cover 9 and in the other direction by the abutment of the shoulders of the tapered section 3f of the front partial section 3a on the shoulders of the section 9e. This path of movement is needed in order to permit the snap hook 9a to engage or disengage from the rectangular recess 7f in the guide rail 7 and the two locking pins 9c of the cover 9 to engage or disengage from the holes 7c of the guide rail 7.

In the rear end of the sleeve 10 is provided a flat recess 10a which is rectangular viewed from below, and which has a projection 10b at one front corner. With this projection 10b cooperates in the joined together state of the front and rear

partial sections

3a and 3b a cutout 3b₁ constructed at the front end area of said latter. This design prevents the rear partial section 3b of the metal band 3 from being inadvertently rotated at 180° about a longitudinal axis with respect to the front partial section 3a.

Two bolts 11 carrying the heads 11a are fastened in the metal band 3 in the area of the recess 10a of the sleeve 10. These bolts 11 extend into keyhole-like recesses in the rear partial section 3b in the connected state of the two

partial sections

3a and 3b of the metal band 3. This position is indicated by dash-dotted lines in FIG. 7.

During the assembly of the guide rail 7 and the front partial section 3a of the metal band 3, the cover 9 is first placed onto the front partial section 3a, with the cover 9 being guided on this partial section 3a by the flaps 9d. The assembly consisting of the

elements

3a and 9 is subsequently moved under the guide rail 7 until its square pin 7g extends into the square hole 3e of the front partial section and the bent web section 3d rests above the hook 7i.

In order to secure the

elements

3a and 9 against separating, the cover 9 is moved slightly forwardly. The cover 9 is thereby locked relative to the guide rail 7 by the two locking pins 9c and the snap hook 9a. With this the assembly of the unit of

elements

3a and 9 for transport and for installation has been completed. Should the ski binding 1, for whatever reasons, be removed from the ski and be disassembled, the guide rail 7 is first released from the ski 2 and the two

partial sections

3a, 3b of the metal band 3 are separated from one another. The snap hook 9a is thereafter on the one hand removed from its recess 7f and on the other hand the two locking pins 9c are at the same time removed from their holes 7c by a spreading apart of these parts, the cover 9 is then pulled off in longitudinal direction from the guide rail 7.

The invention is not to be limited to the illustrated exemplary embodiment. Rather various modifications are possible without leaving the scope of the invention. It would for example be conceivable to arrange only two oppositely lying locking members on the cover, which members act against one another in vertical planes.
